Design and development

The DuckHawk is a development of the Windward Performance SparrowHawk and is intended as a higher performance glider than its predecessor, with very high structural limits and Vne. The DuckHawk has less than 10% parts commonality with the SparrowHawk. It features a cantilever wing, a single-seat enclosed cockpit under a bubble canopy and retractable monowheel gear. [1] [4]

The aircraft is made from preimpregnated carbon fiber. Its 15 m (49.2 ft) span wing employs a Greg Cole-designed airfoil, has an area of 80 sq ft (7.4 m2) and an aspect ratio of 30:1. [1] [5]

Operational history

By December 2016 four examples had been registered in the United States with the Federal Aviation Administration, including three "V" models and one "E" model. [6]

The Fauvel AV.45 was an unorthodox motor glider produced in France in the 1960s and 1970s. Like other Charles Fauvel designs, it was a tailless aircraft, in this case inspired by the work that German firms had done on producing motorised versions of his AV.36 design. The prototype of the AV.45 was an extensively modified AV.36 powered by a Nelson H-59 two-stroke engine. AV.45s have been built with a number of other engines, however, including at least one aircraft powered by a small turbojet. Falconar marketed the plans in the 1970s.
